The Sun Hydraulics NCEBKDN (NCEBKDN) is a versatile needle valve with a reverse-flow check, designed for precise flow regulation in hydraulic systems. This component is fully adjustable, allowing for flow control from fully closed to the maximum orifice diameter, and features an integral high-capacity check valve that enables unrestricted flow from port 2 to port 1. While it is not pressure compensated, it offers easy adjustment even under high pressure due to its balanced adjustment mechanism. The sharp-edged orifice design helps minimize flow variations caused by viscosity changes. This valve is part of the Series 2 cartridges and fits into a T-5A cavity with a capacity of 12 gpm (45 L/min). It can withstand a maximum operating pressure of 5000 psi (350 bar) and has minimal leakage at specified conditions. The NCEBKDN features interchangeable physical and functional characteristics with other two-port flow control cartridges of the same frame size, although extension dimensions may vary. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended; exposure to petroleum-based fluids will damage these seals. Incorporating Sun's floating style construction, this valve minimizes internal binding risks due to excessive installation torque or machining variations. Installation requires specific torque settings: valve installation torque is between 45-50 lbf ft (61-68 Nm), while the locknut torque should be between 80-90 lbf in (9-10 Nm). The adjustment screw has an internal hex size of 5/32 inches (4 mm), and the locknut hex size measures 9/16 inches (15 mm). This product weighs approximately .40 lb (.20 kg) and can be maintained using the Viton seal kit number 990203006.

Needle valves with reverse-flow check are fully adjustable orifices used to regulate flow. They are infinitely adjustable from fully closed up to the maximum orifice diameter. An integral high-capacity check valve provides unrestricted flow from port 2 to port 1. They are not pressure compensated.
- All 2-port flow control cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size). However, cartridge extension dimensions from the mounting surface may vary.
- Because needle valves are non-compensating devices, the fixed orifice size will regulate flow through the valve in proportion to the square root of the pressure differential across ports 1 and 2.
- A balanced adjustment mechanism allows for easy adjustment even at high pressures.
- The sharp-edged orifice design minimizes flow variations due to viscosity changes.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
